In the office now being POC avocent for ACS products, which supposedly he can capture the output from linux. After reading read the documentation of the Linux-Serial finally found it, how to make Linux not just to the monitor output (VGA Card) but via RS232 Console (ttyS0).
1. Make sure your system support serial port.
ttyS0 at 0x03f8 (irq = 4) is a 16550A
ttyS1 at 0x02f8 (irq = 3) is a 16550A
[root@flubber root]# setserial -g /dev/ttyS
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
2. Configure inittab to support serial console login
Before edit /etc/inittab we should make a backup copy.
Now append getty command on inittab file.
s0:2345:respawn:/sbin/agetty -L -f /etc/issueserial 9600 ttyS0 vt100
s1:2345:respawn:/sbin/agetty -L -f /etc/issueserial 38400 ttyS1 vt100
Now, you must activate the changes that you made in /etc/inittab. This is done with the following command, which forces the init process to re-read the configuration file:
Now, let’s make sure that the agetty process is listening on the serial ports:
root 958 1 0 Dec7 ttyS0 00:00:00 /sbin/agetty -L -f /etc/issueserial 9600 ttyS0 vt100
root 1427 1 0 Dec7 ttyS1 00:00:00 /sbin/agetty -L -f /etc/issueserial 38400 ttyS1 vt100
